Hello
So the Set To Next primitive has a obj with category option that lets you find objects by the categories specified in the BCONs 0x0106 & 0x016C, for example 4 returns beds, 28 sinks etc.
So what i want to o is make my own category for my own objects, and so far, i haven't found any value in the OBJD that sets this category. There's Selector Category, but that's used for something else entirely and if you check a bed for example you'll see that it's category is set to 0, not 4.
I'm puzzled, so if anyone's got any ideas i'd love to know

You might be interested in looking at Echo and Phae's costume trunk. IIRC, the trunk is able to expand its catalog of costumes because they created their own "Costume" type and the trunk searches for objects (costumes) of that type to create its menu and then dress the Sim(s).

This worked! i hadn't noticed the category variable before
Thanks a lot
